  Syntheses and Photophysical Properties of Aminobenzopyranoxanthene Dyes Containing Various Alkyl Chains at Amine Moieties

  摘要：

  Aminobenzopyranoxanthene (ABPX) dyes containing linear n-alkyl chains at amino groups were synthesized, and their cis and trans stereoisomers were isolated. Detailed spectrophotometric studies revealed that all the ABPX derivatives exhibited fluorescence emission in the far-red and near-infrared wavelength regions, and their fluorescence quantum efficiency increased with increasing n-alkyl chain length. Almost no differences in photophysical properties were observed between the cis and trans stereoisomers.

  A new class of rhodamine luminophores, 3',3''-bis(oxospiroisobenzofuran)-3,7-bis(dialkylamino)benzopyrano-xanthene derivatives (ABPX), have been successfully developed. The emission behavior of ABPX series is directly opposite to the concentration quenching of conventional rhodamine dyes. ABPX series exhibit aggregation-induced emission enhancement (AIEE).

  已经成功开发了新型的若丹明发光体，即3'，3''-双（氧螺基异苯并呋喃）-3,7-双（二烷基氨基）苯并吡喃基-x吨衍生物（ABPX）。ABPX系列的发射行为与常规若丹明染料的浓度猝灭直接相反。ABPX系列表现出聚集诱导的排放增强（AIEE）。
